OSPF Redistribution route-map with prefix-list not working after upgr

Dear Cisco DevOps for OSPF on ASA,

why has the configuration of prefix-lists been removed from OSPF v3/OSPFv4 when your DevOps colleagues for BGP, IS-IS and EIGRP continue to implement prefix-list?

Furthermore, without prefix-list it is no longer possible to use "less specific" routes as a backup path.
According to the workaround in CSCwi31091, how should it be possible to filter a "less-specific" route via ACL?
Example:
route outside 10.246.2.0 255.255.255.0 [BackupPath-NextHop] 15 <=== DO NOT redistribute
route outside 10.246.2.0 255.255.255.128 [PrimaryPath-NextHop] 10 <= Prefix for redistribution
route outside 10.246.2.128 255.255.255.128 [PrimaryPath-NextHop] 10 <= Prefix for redistribution

Kind regards
Ralf

  • Do not use route maps containing match policy lists for policy based routing. The match policy-list is only used for BGP.

from cisco doc 
MHM

As policy-list is only "supported" for BGP and PBR we still have no solution, regardless the fact that the config is working with OSPF.
Any other solution available?

Any news finding a proper as well supported solution for filtering prefixes without the ASA command "prefix-list" as matching criteria inside a route-map?

Dear Cisco DevOps for OSPF on ASA,

unfortunately, there is still no proper as well supported solution for filtering prefixes without the ASA command "prefix-list" as matching criteria inside a route-map for OSPF.
From my point of view there is no and will never be a proper as well supported solution - except the reimplementation and supporting of the prefix-list for OSPF as it already supported for BGP, IS-IS, EIGRP and RIP.

Any plans from the BA/DevOps to reimplement as well to support prefix-list in OSPF?

Kind regrads
